Energy Recovery Upgrade — Methuen Construction Change Order #2

To approve Change Order #2 to the Energy Recovery Upgrade contract with Methuen
Construction Company of Plaistow, NH in an amount not to exceed $21,181.16 for new
lighting and painting in the energy recover room. Funding will be through: Department:
169- Wastewater; Fund: Wastewater; Activity: Energy Recovery Upgrade Project.

The energy recovery upgrade project involves upgrading all the major components in the
energy recovery room with new generators, piping, heat exchangers, pumps, controls and
associated electrical components. These upgrades are needed since the existing generator
had failed and the other components are beyond their useful life. The project was
awarded to Methuen Construction in December 2018 in the amount of $1,787,378.

Change order 1 was for relocating an expansion water tank and bring electrical
disconnects adjacent to 3 hot water pumps in the boiler room in an amount of $16,742.40.
The new contract total is 1,804,120.40. Change order 2 is for painting and providing new
lighting for the entire energy recovery room in the amount of $21,181.16. This change
order is needed since the energy room has never been painted since constructed in 1999
and existing painted walls have become soiled. The room also has poor lighting making it
a dark room with no windows. New bright LED lighting will allow for safer and better
working conditions.

The new contract value following this change order will be $1,825,301.56
